"There is no legal limit to the number of sponsors an immigrant can have. However, it is essential to note that all sponsors must meet specific requirements to be eligible. They must be 18 years or older, a U.S. citizen or lawful permanent resident, and able to support the immigrant financially.
In addition, all sponsors are required to complete an affidavit of support (I-864) stating that they will provide financial assistance to the immigrants if necessary. They are also responsible for providing information about the immigrants' income, assets, and expenses. This information is used to determine whether the immigrants will likely become public charges (depending on government assistance).
